On the policy part, though, it's tricky. I, again, tend to very much be on the optimistic side of the AI curve, because... Vint Cerf said something long, long time ago that, when the Internet first came out, that we were all way overestimating its short term impact, and underestimating its long term impact on our lives. I feel exactly the same way about AI, that our lives are going to look completely different in 10 years, 30 years, 100 years, than they do right now, because of artificial intelligence, Medicine is the most obvious example, the ability to diagnose breast cancer, lung cancer, now, pancreatic cancer, three and four years ahead of time, that we could never do before. The whole notion of liquid biopsies because of this. That, and medical misdiagnosis, we got a great bill that... apparently 10% of patient deaths every year are due to misdiagnosis. It's something like $10 billion a year. Just think if we took the power of artificial intelligence, combine it with The Checklist Manifesto by Atul Gawande, and look at AI applied to reading the wrong medicine off the chart, or cutting off the wrong arm, or whatever it is, to really move us forward. There's an enormous amount of human good that can come from that, We don't want to take humans out of the loop, we're still going to need doctors, but what we're hearing from the radiologists is that they're much more effective, having AI tools to go with looking at the X rays, or the mammograms, or whatever else.
